Abstract

A NIR luminescent octanuclear Zn(ii)-Nd(iii) nanocluster 1 was constructed by the use of a salen-type Schiff base ligand. 1 exhibits a lanthanide luminescent response to Que with high sensitivity. The quenching constant of Que to the lanthanide emission is 2.6 × 10 M, and the detection limit of 1 to Que is 2.5 μM. The response behavior of 1 to Que is not affected by the existence of some potential interferents such as biomolecules.

摘要

通过使用一种席夫碱型配体构建了一种近红外发光的八核锌（II）-钕（III）纳米团簇1。1对奎宁表现出高灵敏度的镧系发光响应。奎宁对镧系元素发射的猝灭常数为2.6×10 M，1对奎宁的检测限为2.5 μM。1对奎宁的响应行为不受一些潜在干扰物如生物分子存在的影响。
